SPECIFICATION forming part of Letters Patent No. 654,379, dated July 24, 1900. Application filed llpril 80, 1900. Serial No. 14,868. (No model.)

To aZZ whom it may concern.-

Be it known that We, HEINRICH BETTEN- DORE, mechanical-instrument maker, residing at 2 Hochster street, and JULIUS MAX BIER,

merchant, residing at 53 Zeil, Frankfort-onthe-Main, in the Province of Hesse-Nassau and Empire of Germany, both subjects of the Emperor of Germany, have invented certain new and useful Improvements in and Relating to Type-Writing Machines and the Like,

of which the following is a full, clear, and exact description.

This invention, which is hereinafter described, and illustrated in the accompanying drawings, relates to typewriting machines and the like, and has for object to enable each key to write two characters without having to be shifted, whereby a more simple manipulation and more rapid writing are intended to be obtained. For this purpose each key is connected with two type-levers, type-rods, or type-carriers in such a manner that these, in addition to their movement in a vertical direction, make a movement in a horizontal 2' 5 direction, and by means of this last movement bring the second type into the writing or printing position.

The accompanying drawings illustrate this invention in its various positions of working 0 applied to a type-lever type-writing machine.

Figure 1 shows the position of rest of the device. Figs. 2 and 3 show each a type-lever in the printing position. i Fig. 4 shows the front view of the device in a section taken 3 5 through the key-guiding device f. Fig. 5

shows the key in plan view.

As will be seen from Figs. 2 and 3, the key t is mo vably connected or jointed at the lower end of the shank of the key in a suitable o manner by means of the key-lever vZ1 to the type-lever a, While in the vicinity of the up per end of the key-shank there is engaged with a stud Z a rod or link a, formed with an elongated slot g, while the other end of this rod acts upon the type-lever (Z. The connection between the key and the type-lever is now such that a vertical pressure exerted upon the key t, Fig. 2, will cause the type-lever c to enter in operation, while the type-carrier 5o cl remains in its position of rest, because the stud Z of the shank slides along in the slot g of the rod or link. After the key 25 is released the spring a draws the key-lever 3) back again into the position of rest. A spring 2 holds the key shank in the proper position against the rear guiding edge of the frameplate f, and the pins 2' of the slot 19 of the rod on then prevent any movement of the latter.

The movement of the type-lever d by the' horizontal movement of the key i will be clearly seen from Fig. 3 in this case, the movement of the key producing only a shifting of the rod a by means of the stud l, which shifting, by means of the pins c' in the guide 19, can always take place in a horizontal div rection and which is transmitted to the typelever d and presses the latter against the roller w.

What we claim, and desire to secure by Letters Patent, is 7o 1. A type-writing machine constructedsubstantially as herein described with fingerkeys capable of both vertical and horizontal movement and two type-bar levers connected to each finger-key by a vertically-vibrating lever, and a horizontally-slidable bar respectively, whereby movement is imparted to one of said type-bars by vertical movement of the key and to the other type-bar by horizontal movement of the key as explained.

2. The combination of a finger-key i, capable of both vertical and horizontal movement,

a pair of type-bar levers o, d, a vibrating lever 5, pivoted at its respective ends to the finger-key t, and the type-bar lever cl, and

the slidable bar a, connected at its respective ends to the finger-key t, and the type-bar lever d; whereby the vertical movement of the finger-key imparts printing movement to the type-bar lever c, and the horizontal move ment of the finger-key imparts printing movement to the type-bar lever '61, substantially as described.

3. The combination of the finger-keyt, capable of vertical and horizontal movement; two type-bar lovers 0, and cl; the vibrating lever 19, pivoted at one end to the finger-key t, and at its other end to the type-bar lever c; and the slidable bar a, coupled at one end to the type-bar lever d, and at the other, by roe a slot connection, to the finger-key t; where- In witness, whereof we subscribe our Sign? by the Vertical movement of the finger-key tures in presence of two'witnesses. is permitted to impart printing movement to HEINRICH BETTENDORF. the type-bar lever a, While the bar a is at JULIUS MAX BIER. 5 rest, or horizontal movement of the finger- Witnesses: key is enabled to actuate the slidable bar a, JEAN GRUND, and type-bar lever d, as explained; RICHARD GUENTHER.
